Energy efficiency potentials in industrial motor systems are massive, in particular if a system optimization approach is pursued. Furthermore, many of the energy efficiency investments have payback times of a few years only.
Developing countries with high growth rates and a fast growing industry can benefit from poli- cies for energy efficient motor systems. Using system optimization tools and high efficiency components for the construction of new production plants is the least costly and most efficient way to improve energy efficiency. Many of the components have lifetimes of up to 20 years and not choosing energy efficient components implies inefficient production for a long period of time and makes future optimization more costly. This is an advantage developing countries have in comparison to developed countries, where a – sometimes several decades old and less effi- cient – technological production structure has been established and energy efficiency improve- ments often are more expensive, because they require substantial system changes or are not even possible to realize because they would require an interruption of the production process.
Policies to improve motor system efficiency are in place in many countries worldwide and ex- amples have been introduced here. The BRICs countries like China or Brazil have implemented policies like minimum energy performance standards for electric motors on the market, as well as audits and energy management standards. The latter are particularly useful for addressing the huge saving potential that lies in system optimization. The success of audits and energy man- agement in industrial facilities is closely bound to the availability of skilled staff and experts. The needed experts are particularly scarce in developing countries and capacity development programmes related to motor system optimization are indispensable to further promote energy efficiency in these countries.
Still, in both developed and developing countries, the policies in place are insufficient to exploit the energy efficiency potentials of motor system optimization.
